positioned for engagement with the contentsof the car in auch manner as to prevent the contents from shifting, engagement being effected without marring or injuring the contents. Y

Another object of the invention is the provision of a freight chock which is stron and durable in construction, easily handle and readily secured in position for use, and which in addition may be stored in an out of the way place when not in use.

nother object of the invention is the rovision of means of the above-character w ch in addition to functioning as a chock, will serve to resist any bulging tendency of the car walls.

`With the above and other objects in view, the invention further includes the following novel features and details of construction, to `be hereinafter more fully described, illusdrawings and pointed out in the appends claim.

In the drawings-,-

Referring to the drawings in etail wherein like characters of-reference denote correspon'ding indicates t e side walls of a freight car and 11 the doors which are positioned centrallyl of the sidewalls.y The car walls are sealedv in the lordinar manner as indicated Vat 12. Included in t e sealing 12 are preferably metal stri s 13. These strips are Cpreferably inset as shown in Fi' res 1 an 3 'of the drawings and the sealing 12 is spaced from the upper edges of these strips so as to pro- -mgs 19 and 20 are adapt plarts, the reference character vide ves 14. 'The strips 13 may be horizon y spaced and any number suitable may be employed.

The choc one of which is illustrated in Figure 4 of t e drawings, comprises a beam 15. This beam is adapted to be horizontally arranged and is substantially wedge shaped .Y u

1in cross section so that its engaging edge 16 'is relatively wide.

n This provides a broad face for engagement with the contents of the car to reduce danger of injury to said contents and without unduly increasing the wei t of the beam. Secured to each end of the am 15 is a beam carrier in the form of a panel 17 Extendin along the outer face of the panels 17 are orizontally arranged tongues or ribs 18 which enter the ooves 14 and are slidable along the u per e es of the strips 13, so that the choc may 'forced into position against the freight to hold the latter in lace. l

In or er to prevent movement of the chock, the panels 17 are provided with spaced openings 19 which are adapted to register with horizontall and vertically spaced openings 20 provide in the stri s 13. Theopen u to receive bolts 21, which threadedly engage the openings 20 and in addition to holding the chock in position, act to resist any tendency of the car walls to bulge outward. Pins 22 which are secured to flexible members 23 carried by the panels 17, are adapted to enter openings 24 provided in the heads of the bolts 21 tohold `the latter in position. of the cho cks showing the beam partly broken and to resist any tendency of the car walls to bulge outward. When not in use, the chocks are supported in an out of the way position adjacent the top of' the car. For this purpose, the sealing 12 1s provided withspaced openings 25 which are adapted to receive extensions 26 at the'ends'of the panels 17. Hooks `28 are pivotally secured to the top of the car so as to engage beneath the edge of the beam 15 as shown in Figure 1 and 3 of the draw- 111 j. A l ghe strips 13 include removable sections 29 A which are adapted to extend across the door-- way of .the car. These sections '29 have an overlapping engagement as shown at with the adjacent ends of the strips 13 and are removably secured in position by means of screws 31. When not in use, the sections 29 are supported beneath the top of the car by means of downwardly extending bolts 32 which pass through the openings 2O of the sections 29 and which have mounted thereon securing nuts 33.

It will be noted by reference to Figure 2 of the drawings that the openings 20 are arranged in double rows, so that the bolts 21 may be engaged in the upper double row of openings With the ton ues or ribs 18 upon the upper edge of the strips 13, or, the position of the beam l5 may be reversed, that is, the tongue or ribs 18 may be positioned along the lower edge of the strip 13 with the bolts 2l engaged in the lowermost o enings. provides another adjustment orthe beam.

This

ing a beam, a slidable beam carrier at each end of the beam, means carried by and eX- tending throughout the length of the car upon opposite sides thereof to slidingly engage the beam carrier and permit said beam to be horizontally adjusted, a removable section ineluded in the car carried means and to secure the beam in adjusted position.

In testimony whereof I affix my signature.
